The present "invention provides an improved stove that -is "arranged forcookingand baking and-wlth the embodiment ofcertain fea- -tures andarrangement "oi constructiom-the room or enclosure in 'w-hich the-'stovelslocated is effectively illuminated.

The fuelfor the stove maybe a" suitable oil, manufactured or natural.gas, or electricity.

"The outstanding advantage *of the invention .is the fact that due to.the scientifically-arranged combination of three sources *ofut1lity;-namely heating, cookingand lighting,- the invention pre- "sentsa new era and transformation from an economical viewpoint-,jnthisparticular field of industry.

. Further readily apparent during coming detailed description,

advantages "of the invention will. be

the course of the forththroughout-the acis located directly under therespective burners An oil drip pan I6 is employed for each -of saidburners and is secured thereto as shown in Figure 9. A door I1 isarranged for each of said fuel chambers and each door being mounted onhinges, and having a suitable door handle I9;

said doors being adapted to close the openings in the'respectivechambers in a substantially tight "manner. A plurality of elongatedwindows .are provided in each of doors H and are closed with heat-prooftransparent material.

' Referring more particularly to Figures 8 and 9 it is observed that adouble baffle member 2| is provided with its underside forming theceiling of fuel chambers I; said member being preferably a suitablehollow casting, provided with openings within the top portion thereofwhich are adapted toreceive stove lids 22 where indicated. There'companying illustrative drawings, and'more particularly pointed-out'inthe {appended claims.

Figure 9 is a-longitudinal section takenupon line 9+9 of Figure 3.

Figure 10 is acompletefiviewof the bottom of the device and showing theunderai-r draught control.

The invention comprises a metal casing :or :enclosure having front panel'side panels 2, rear panel- 3, top" 4 and bottom 5, and with-legs formedas at 6.

Fuel chambers l arerormed by a=bottomwall 5, rear wall 8, side walls 9and a common partition Ill, forming thereby two independent chambers.Within said chambers suitable burners II are positioned as shown inFigures 8 and 9, with fuel supply lines |2 for the respective burners,being provided.

Within bottom 5 openings l3 are provided so as to accommodate under airdraught levers I4, said levers being pivotally secured to bottom 5 as atl5, and it is seen that said under draught is an opening 23 in theunderside of baffie member 2| directly over the burner in each of the--fuel chambers I, and in axial alignment with -the cor-responding lidopening, so that the heat from the burners will directly contact saidlids.

A spacious oven 24 is provided with a suitable -door25, having pulls 26therefor as shown. The door being pivotally connected to members 21,

which are adapted to slide upon rails 28 within "the top portion of thedevice when said door is --opened, as indicated by the dotted lines inFigure 8.

An opening 29 is arranged in door and is closed by a suitabletransparent heat-proof -material. The oven is provided with a curved--metal back 30, which extends to a point ad- --jacentthe bottom of thecasing with its lower portion formed as shown at 3|. The inner surfaceback 30 and the portion 3| thereof are pro- -vided with a high polishand mirror finish from reflecting surfaces.

Refiectors'32 and 33 are also provided in vertically spaced cooperativerelationship on each of the side walls of the casing; the reflectors 33--'the fuel chambers and the reflectors 32 being opposite the windows4|] in the upper side walls of the casing which have their innersurfaces being opposite the windows in the side walls of v Referring toFigures 5, 8 and 9, a screened grate 35 is provided and is removablypositioned within oven 24 as indicated; Said grate may be readilyremoved for cleaning purposes. The oven chamber is formed by the backWall 30, the top of the bafiie member 2| and side walls 36.

The fumes and objectionable gases are discharged from the interior ofdouble baiile member 2| by means of pipe 31, which leads to the housechimney A, as indicated in Figure 8. In Figure 4 pipe 37 is shown ashaving a funnel shaped end as at 33 communicating with both divisions ofthe interior of double baiile member 2! so that combustion gases aresimultaneously discharged from such compartments.

In Figure 10 it is seen that bottom 5 of the device is substantiallybraced to side panels 2 and rear panel 3 by means of braces 33 asindicated.

An opening 43 is provided in each of the side panels 2 at pointsdirectly above the reflectors 33. Openings 41 are provided in the rearand side walls of the fuel chambers 7 directly opposite the reflectors3i and 33 and are covered with heat-proof transparent material.

For baking purposes door is pivotally elevated by means of knobs 26thereon and is slidably moved inwardly upon rails 28, as clearly shownby the dotted lines in Figure 8, the utensils with the baking materialare then placed upon removable grate 35, and the oven door accordinglyclosed. In Figure 9 it is clearly indicated by the arrows, how theintensified heat from burners II is baflied by reason of the lowerportion of bafile member 2| and said member having upper and lower wallsprovide a bailiing chamber for each of fuel chambers I through openings23 within the lower walls of said member. An opening or window 29 withindoor 25 affords adequate facility for viewing the baking within oven 24admitting of the proper attention required.

While oven 24 is entirely enclosed there will be suflicient heat withinthe upper portion of the stove to provide for ordinary cooking, and forthis purpose the elongated openings 42 are arranged within top 4, asclearly indicated in Figure 3.

It is understood that the design and exterior finish of the stove isvery attractive, and may be placed within the parlor, or in fact withinany suitable location of the dwelling, and by virtue of door 25 beingadapted to open as previously explained, and when in an opened positionas shown by the dotted lines in Figure 8, and by reason of the curvedback 328 of the oven, the stove becomes an attractive radiant heater.

Referring to Figure 9, the heat from burners I I will radiate throughflue passages 43 and out through opening 45 within each of side panels2, as shown by the arrows in this view, consequently it is understoodthat the device provides a very effective heating unit that is capableof heating an entire dwelling consistent with space to be heated and theproportional size of the stove used. The heat is greatly intensified byvirtue of reflectors 32 and 33 and back 33.

An additional advantage and a novel feature of the invention is theilluminating qualities it reflected into the room.

possesses. This is accomplished by means of windows 4| that are locatedwithin the respective walls of fuel chambers 1, and again referring toFigure 9 the arrows therein indicate how the light from burners llpasses through said windows and simultaneously upon reflectors 3| and33, and the reflection of said light upon reflector 3! will in turn bereflected to back as indicated by the arrows in Figure 8, and when door25 of oven 24 is closed the last-named light rays will pass out into theroom through window 29 within said door. When door 25 is opened then theentire benefit of reflector back 30 is obtained for light into the room.

The light rays through windows 4| from bumers I I upon reflectors 33will in turn be reflected 'upon'reflectors 32 by virtue of uninterruptedflue passages 43, thence outwardly through openings 48 within sidepanels 2 and into the room. Thus it is understood that the same elementsand arrangement thereof effect a combination for the scientific resultof both heating and lighting for the intended purpose. It is to befinally understood that the lighting effect of the invention would beconfined to the room in which it is to: form therebetween air heatingpassages; a win-r dow in the rear wall and in one of the side walls ofeach of said fuel burning chambers; a window in each side wall and inthe front wall of said casing and vertically spaced above saidfirstnamed windows; and a reflector positioned oppo-' site each window;the reflectors opposite the casing windows cooperating with thoseopposite the fuel burning chambers to reflect the light rays therefrominto the room.
